〔産業上の利用分野〕
本発明は、軽車輌用キヤスト（鋳造）ホイール
の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a cast wheel for a light vehicle.
従来の軽車輌用ホイールには大別して二種類存
在する。一つは、ホイール全体を鋳物で成形する
もので、他の一つはその全体を鋼板で成形するも
のである。
Conventional wheels for light vehicles can be roughly divided into two types. One type is one in which the entire wheel is made of cast iron, and the other is one in which the entire wheel is made of steel plate.
鋳物成形するホイールは、それぞれ別々に鋳造
成形された軸受ボスとブレーキドラムを鋳造機に
取付けられた固定金型に植え込み、可動金型を型

て、この一体物にリムをボルトによつて締付け固
定している。 For wheels to be cast, the separately cast bearing boss and brake drum are placed in a fixed mold attached to a casting machine, and after the movable molds are aligned and clamped, aluminum die casting is poured through a sprue. It is boiled and taken out after cooling. The rim is then tightened and fixed to this integrated body with bolts.
又、鋼板製のホイールは、各部材をプレス加工
によつて成形し、それらを溶接によつて一体化す

作業が必要となつている。従つて、多くの工程を
必要として成形費が嵩み、生産性が悪いという問
題を有している。[Problem to be Solved by the Invention] However, in the case of cast wheels, the bearing boss and the brake drum are molded separately, and each is separately placed in a mold and poured. In this case, misalignment and deflection of the bearing boss and the brake drum often occur due to the influence of the pressure of the hot metal during pouring and the cooling rate of the poured aluminum die-casting differing in different parts of the mold. Therefore, after taking out the wheel, it is necessary to machine and finish the inner and outer diameters of the bearing boss, the inner diameter of the drum, or the portion to which the rim is attached. Furthermore, it is necessary to assemble the rim to this integrated body. Therefore, there are problems in that many steps are required, the molding cost increases, and productivity is poor.
又、鋼板製のホイールにあつては、ブレーキド
ラム等が肉薄であるために、ブレーキをかけた際
にブレーキドラムが振動して、いわゆるブレーキ
鳴きの現象が発生するという致命的な欠点があつ
た。 In addition, steel plate wheels have a fatal drawback in that the brake drums and other parts are thin, which causes the brake drums to vibrate when the brakes are applied, resulting in so-called brake squeal. .
本発明はこうした問題に鑑み創案されたもの
で、生産性が良く、かつブレーキ鳴きの発生しな
い軽車輌用キヤストホイールの製造法を提供する
ことを、その課題とする。 The present invention was devised in view of these problems, and an object of the present invention is to provide a method for manufacturing a cast wheel for a light vehicle that has good productivity and does not generate brake squeal.
そのための手段として、まず鋼板製ブレーキド
ラムと軸受ボスとを組付けることによつて形成さ

た。
As a means for this purpose, first, a hub formed by assembling a steel plate brake drum and a bearing boss is fitted into a mold. After that, the spoke part 2 is formed by pouring the metal into the mold.
is welded to the hub. After cooling, the integral hub and spoke portions 2 were taken out of the mold, and then the steel plate rim 3 was assembled to the spoke portions 2 with screws.
鋼板製のブレーキドラムと軸受ボスとを組付け

係が安定した姿勢に保たれる。このブレーキドラ
ムと軸受ボスとの一体物を鋳型内に植え込み注湯
するが、両者は一体化して相互位置姿勢が安定し
ているので、湯圧によつて両者の姿勢が崩れるこ
ともなく、又、湯の冷却度の相違による影響によ
つて撓むこともない。
By assembling the steel plate brake drum and the bearing boss, the two are integrated and their mutual positional relationship is maintained in a stable posture. This integral part of the brake drum and bearing boss is placed in a mold and poured into the mold, but since the two are integrated and their relative positions and postures are stable, their postures will not collapse due to the hot water pressure. , and will not warp due to the effects of differences in the degree of cooling of the hot water.
従つて、従来のように多くの後加工を必要とせ
ず、生産性が向上する。 Therefore, much post-processing is not required as in the conventional method, and productivity is improved.
さらに、鋼板製のブレーキドラムはダイキヤス
トによつて被覆され肉厚となるので従来のような
ブレーキ鳴きが生じないと共に、肉厚となつたこ
とで機械的強度も増す。又、ブレーキドラムを肉
薄の鋼板製として従来の鋳物製と比較して肉薄と
したことことによつて、その分、軽量化が図れて
いる。 Furthermore, since the brake drum made of steel plate is coated with die-casting and has a thick wall, it does not generate brake squeal unlike conventional brake drums, and the thicker wall also increases mechanical strength. In addition, by making the brake drum made of a thin steel plate, which is thinner than conventional casting, the weight can be reduced accordingly.
又、リム３を鋼板製として、鋳型で成形された
スポーク部２にネジ１２で組付けることとしてい
るので、従来のリムをも鋳型内で成形する技術と
比較して鋳型が簡易なものとなり、製作上有利で
ある。 In addition, since the rim 3 is made of a steel plate and is attached to the spokes 2 formed in a mold using the screws 12, the mold is simpler than the conventional technology in which the rim is also molded in the mold. It is advantageous in terms of production.

The spoke portion 2 is made of aluminum die casting. This aluminum die casting is welded to the outer peripheral surface and side end surfaces of the brake drum, and to the peripheral end of the bearing boss. A plurality of torque locks (not shown) are formed on the brake drum 2 and the bearing boss 1 to further strengthen the assembly with the aluminum die cast. A torque lock is a so-called anti-slip device, for example, a plurality of holes are provided at appropriate locations on a brake drum, die-casting is poured into the holes, and the two are engaged to prevent slipping.
リム３とスポーク部２との組付けはネジで行う
が、これは通常のネジ１２であつても良いし、
又、螺旋付打込鋲１１であつても良い。 The rim 3 and spoke portion 2 are assembled using screws, but these may be ordinary screws 12 or
Further, the driving stud 11 with a spiral may be used.

いる。 As shown in FIG. 2, a rim torque clock 13 consisting of numerous irregularities is formed on the inner circumferential surface of the rim, thereby increasing the frictional resistance with the outer circumferential surface of the spoke portion 2, thereby facilitating assembly. It is made more solid.

In this way, the present invention involves assembling the steel plate brake drum and bearing boss, placing them in a mold, and integrally molding the remaining parts by die casting. It is possible to provide highly productive wheels that do not require processing.
又、ブレーキ鳴きがなく、機械的強度に優れ、
軽量である。 In addition, there is no brake squeal, and it has excellent mechanical strength.
It is lightweight.
